IGBT Discretes

Hi all,

The Ic(sc) of IKD15N60RF is described as 112A in the data sheet.
Is there a recommended current value to protect the short circuit?
As a condition, they keep the short circuit time.

Best regards,

选择1ED020I12-F2驱动IKW15N120H3，当母线电压300V时，栅极驱动信号上升过程中有较大震荡，此现象如何有效改善？

Hi all,

Regarding IKD15N60RF, could you please tell me the max values of trr, Qrr and Irrm both Tvj = 25 ℃ and 175 ℃?

Best regards,
MS

Hi all,

I think that the waveform under the IC (SC) conditions described in the data sheet of IKD08N65ET6 is as follows.

Is it correct?

Best regards,
MS

Hi all,

Could you please tell me if IKA15N65ET6 conforms to UL QQQX2?
Also, please let me know if there is a way to check it by myself.

Best regards,

MS

Dear Infineon,

We want  to use SGB07N120 at linear area as high voltage linear drop output. Of course, the output current of high voltage LDO is very low, e.g. 5mA.  Do you think SGB07N120  can work as linear area. If yes, do you have FBSOA of  SGB07N120  ?

BRs,

Dear all

We used here in the company the 1ED020I12-F2 driver and IRFPG4063 in a full bridge inverter (bus voltage 400 Vdc, output 220 Vac 60 Hz).
The gate resistor are 22R, the RC in the desat pin is 470R resistor and 220pF capacitor, with a diode UF4007 in the collector of each IGBT.
The power supply is single, 15 Vdc, the miller clamp pin is connected directtly in the gate of each IGBT. The operation frequency is 20 kHz.
This solution works very well. But the 4063 IGBT is obsolete, so, our distribuitor offered the alternative of IKW50N65H5 IGBT.

With the same configuration, this IGBT doesn´t support the short circuit test. I try change the RC in the desat pin to 100R and 100pF
without sucess.

The peak current in IGBT during short circuit is about 140A, i believe that this value is very close of the maximum capacity of IKW50N65H5.

What can i do to use this alternative IGBT in circuit?

Sincerelly
